Is it safe, with respect to the data on a USB drive, to power it down while the computer is suspended, and then power it back up before resuming? E.G. are buffers on the USB drive flushed as part of the suspend procedure? Are there likely to be any other unfortunate side effects?
Specifically under Maverick "10.10" Meerkat, with an IDE (PATA) drive, but of course it would be useful to get info on a variety of setups.
Note: by "suspend" I mean the S3, "mem" sleep state. However, answers pertaining to hibernation (S4) would also be helpful.
